2. Look at the bottle stopper. In fact, many people don't know that we can judge the quality of wine by the cork of a red wine bottle. Generally speaking, if the cork of a wine is tightly sealed and looks very rough, then the quality of this wine is not good. If the cork of a wine is sealed with wax, and the brand logo is also marked on it, then this wine is generally a good quality red wine, and if you open the cork, the bottom of the cork will have a sign of productivity.
3. Look at the color of the wine. In daily life, wine is actually divided into red wine and white wine, so we can put the wine in the sun. Generally speaking, the wine with better quality is very bright, and there will be no precipitation. It looks particularly full and natural. If the color is dark brown, then this red wine is of poor quality, and if it is white wine, it should be golden yellow and particularly bright in the sun.
4, drink wine taste. Of course, the last point is that only people who drink wine often can feel that, generally speaking, if a glass of wine is very smooth and tastes a faint aroma, it means that it is a good quality wine, but if it feels sour and even stings the throat, it is a poor quality wine.
